Recently, some departures from the ΛCDM model have been reported by WMAP and Planck satellites such as suppression of the lowest CMB multipoles, the hemispherical asymmetry in CMB anisotropy plan, etc....

The search for weakly-interacting massive particle (WIMP) dark matter is multi-pronged. Ultimately, the WIMP-dark-matter picture will only be confirmed if different classes of experiments see consistent...

The absence of a neutrino flux from self-annihilating dark matter captured in the Sun has tightly constrained some leading particle dark matter scenarios. The impact of astrophysical uncertainties on...

In this paper, we give a detailed user’s guide to the AMIDAS (A Model-Independent Data Analysis System) package and website, which is developed for online simulations and data analyses for direct Dark...

We use cosmology-independent measurements of the expansion history in the redshift range 0.1≲z<1.2 and compare them with the Cosmic Microwave Background-derived expansion history predictions. The motivation...

The field of astroparticle physics is currently the focus of prolific scientific activity. In the last decade, this field has undergone significant developments thanks to several experimental results...

The current flow of high accuracy astrophysical data, among which are the Cosmic Microwave Background (CMB) measurements by the Planck satellite, offers an unprecedented opportunity to constrain the...

We present MadDM v.1.0, a numerical tool to compute dark matter relic abundance in a generic model. The code is based on the existing MadGraph 5 architecture and as such is easily integrable into any...

In the last few years many advances have been made in the field of dark matter direct detection. In this article I will review the progress and status of experiments that employ detection techniques...

Most of the neutrino oscillation results can be explained by the three-neutrino paradigm. However several anomalies in short baseline oscillation data, corresponding to an L/E of about 1 m/MeV, could...

The first direct observation of gravitational waves’ action upon matter has recently been reported by the BICEP2 experiment. Advanced ground-based gravitational-wave detectors are being installed. They...

A short review on the next-generation experiments aiming to study the neutrinos produced in cosmic-ray induced atmospheric showers is presented. The projects currently proposed rely on different complementary...

Cosmological observations and the dynamics of the Milky Way provide ample evidence for an invisible and dominant mass component. This so-called dark matter could be made of new, colour and charge neutral...

This paper reviews solar neutrino observations interpreted in the context of the Solar Standard Model and neutrino oscillations. Solar neutrinos have been detected since 1968. Early results showed a...

The indirect detection of particle dark matter (DM) is based on the search for anomalous components in cosmic rays (CRs) due to the annihilation of DM pairs in the galactic halo, on the top of the standard...

Neutrinoless double beta decay is a lepton-number violating process predicted by many extensions of the standard model. It is actively searched for in several candidate isotopes within many experimental...

The axion is both a compelling dark matter candidate and provides an elegant solution to the strong CP problem. The axion haloscope technique has the potential to detect dark matter axions. ADMX (the...

Recent measurements of the neutrino mixing angle θ13 cap a decade of observations which have clearly established the oscillation of neutrino flavor. Measurements of reactor ν¯e disappearance over ∼km...

One hundred years after their discovery by Victor Hess, Cosmic Rays are nowadays subject of intense research from space based detectors, able to perform for the first time high precision measurement...

Experimental efforts to reveal the nature and origin of cosmic rays with energy above 1018 eV led to several important steps forward in recent years. The existence of a suppression of the flux above...

Before the end of this decade, three competing experiments (ALPHA, AEGIS and GBAR) will discover if atoms of antihydrogen fall up or down. We wonder what the major changes in astrophysics and cosmology...

Weak lensing by large scale structure or ‘cosmic shear’ is a potentially powerful cosmological probe to shed new light on Dark Matter, Dark Energy and Modified Gravity. It is based on the weak distortions...

We introduce a string-inspired model for a bouncing/cyclic universe, utilizing the scalar–tachyon coupling as well as contribution from curvature in a closed universe. The universe undergoes the locked...

We argue that there is an intrinsic noise on measurements of the equation of state parameter w = p/ρ from large-scale structure around us. The presence of the large-scale structure leads to an ambiguity...

Questions regarding the formation of the Universe and ‘what was there’ before it came to existence have been of great interest to mankind at all times. Several suggestions have been presented during...

With the nine-year data release of the Wilkinson Microwave Anisotropy Probe (WMAP9), it is found that the inflationary models with the scalar spectral index ns ≥ 1 are excluded at about 5σ confidence...

We use recent measurements of the expansion history of the universe to place constraints on the parameter space of cubic Galileon models, in particular we concentrate on those models which contain the...

We discuss a cosmological model where the universe shrinks rather than expands during the radiation and matter dominated periods. Instead, the Planck mass and all particle masses grow exponentially,...

Recent observations indicate that about half of the dwarf satellite galaxies around M31 orbit in a thin plane approximately aligned with the Milky Way. It has been argued that this observation along...

We use the latest Planck constraints, and in particular constraints on the derived parameters (Hubble constant and age of the Universe) for the local universe and compare them with local measurements...

The mass of primordial dark matter (DM) protohalos remains unknown. However, the missing satellites problem may be an indication that they are quite large. In this paper, we use effective field theory...

Based on observational tests of large scale structure and constraints on halo structure, dark matter is generally taken to be cold and essentially collisionless. On the other hand, given the large number...

In this note we establish LHC limits on a variety of benchmark models for hidden sector physics using 2011 and 2012 data. First, we consider a “hidden’’ U(1) gauge boson under which all Standard Model...
